Horn Fuse

My 49 F1 is converted to 12V, all the wiring diagrams I've seen show no fuse for the horn, just a relay going to 12V supply. What protects the wire if the relay fails shut?

A fuse wouldn't shut the horn power down, because the current wouldn't be excessive. The only cure is to get the hood up and snip the wire or bang on the relay.
